Gruvlok Grade EP EPDM Gasket
Gruvlok® Figure 7003 Hingelok® Coupling with Grade "EP" EPDM Gasket
The Gruvlok® Figure 7003 Hingelok® Coupling with Grade "EP" EPDM Gasket is a high-performance mechanical grooved coupling designed for applications requiring rapid pipe connection and disconnection while maintaining a secure, leak-resistant joint. Ideal for systems that require frequent maintenance, inspection, equipment replacement, or temporary piping, the Figure 7003 combines a permanently hinged housing with a cam-action locking mechanism to minimize installation time and downtime. Rated for working pressures up to 300 PSI (20.7 bar), this coupling is widely used in commercial plumbing, HVAC systems, industrial processing, municipal water systems, mining, water treatment facilities, and mechanical piping installations.
When equipped with the Grade "EP" EPDM gasket, the Figure 7003 provides outstanding sealing performance for water-based systems and many non-petroleum industrial applications.
Quick Installation with Hinged Design
Fast Maintenance and Reliable Pipe Connections
The Figure 7003 features permanently hinged coupling halves that simplify handling and eliminate loose components during installation. A cam-action locking handle allows the coupling to be quickly secured over grooved pipe without additional tools, while a locking pin provides extra security for critical applications. This innovative design significantly reduces maintenance time while ensuring a dependable mechanical pipe joint.
Compatible with standard grooved steel pipe, fittings, and valves, the Hingelok® Coupling offers an efficient alternative to welded, threaded, or flanged connections.
Grade "EP" EPDM Gasket
Engineered for Water and Chemical Service
The Grade "EP" EPDM gasket, identified by its green and red color code, is manufactured in accordance with ASTM D2000 and provides a service temperature range of -40°F to 250°F (-40°C to 121°C). It is recommended for water service, diluted acids, alkaline solutions, oil-free compressed air, and many non-petroleum chemical applications.
For hot water systems, Gruvlok® recommends using Gruvlok® Xtreme Temperature Lubricant during installation to maximize gasket performance and extend service life. The Grade "EP" gasket is also NSF/ANSI 61 Certified for cold and hot potable water applications through 12-inch pipe sizes, making it suitable for drinking water systems.
Grade "EP" EPDM gaskets are not recommended for petroleum products, fuels, oils, or compressed air containing oil vapors.
